FIPSSQ? 3R RUSS liltihlitlibt .hltl litbl-l nuuta United States Patent METHOD FOR REMOVING BURNS OR SCORCHED PARTS FROM CLOTH WITHOUT REMOVING THE COLOR BY APPLYING WAX, ZINC OXIDE, AND HYDROGEN PEROXIDE Mary Broos, Euclid, Ohio No Drawing. Application July 22, 1955, Serial No. 523,938

3 Claims. (Cl. 23-137) This invention relates to a method for removing burnt or scorched spots from cloth without removing the color from the cloth and consisting in covering the burnt or scorched spots with powdered paraffin wax and zinc oxide and sprinkling or moistening the powdered mass with hydrogen peroxide and then rolling the cloth into a roll and allowing it to stand for about one hour and repeating the process if necessary.

At the present time, it has been very diflicult and practically impossible to remove the burnt or scorched effects from cloth without removing the color of the cloth and it is an object of this invention to overcome this difiiculty.

The invention consists in the novel method and materials used as hereinafter described and more particularly pointed out and described in the appended claims.

According to this invention, the burnt or scorched cloth is laid upon a level base such as a table and the burnt or scorched area is covered with powdered material consisting of a combination of paraflin wax and zinc oxide. Hydrogen peroxide of proper grade is then sprinkled over the powdered material, the cloth is then rolled up and allowed to stand for about an hour or so.

The powdered material may be made from melting paraflin wax and stirring therein approximately 8.0% fine zinc oxide until the mass cools. The cooled mass can then be cut into suitable pieces that can be finely ground to produce the combination of powdered wax and zinc oxide. Thus the powdered mass will consist of approximately 92% paraflin wax and 8% of zinc oxide.

The hydrogen peroxide used consists of active ingredient, hydrogen peroxide, 3%; inert ingredient, water 97%; it is a solution commercially known as 10 Volume which will not injure cloth.

In carrying out this novel method or process, the cloth with the burnt area or spot is spread upon a level base such as a table, then about a tablespoon or one part by volume of finely ground paraffin wax and zinc oxide of the composition stated is applied as by sprinkling over the entire burnt area, then about two tablespoonfuls or two parts by volume of hydrogen peroxide of the concentrated stated is sprinkled over the powdered composition of wax and zinc, then the cloth is rolled up and allowed to stand for about an hour depending upon the material treated. After about an hour, the cloth can be examined to determine whether the burnt etfect has been removed. In the event that some slight brownish color still exists, the cloth should be given a second treatment. When the brownish color has disappeared which usually occurs during the first treatment, the cloth is unrolled and thoroughly rinsed of whatever remains.

The method has been successfully used on woolen cloth and cotten cloth with very satisfactory results. But it may be used in the treatment of other kinds of cloth, which respond to the materials used.

In practice, it has been found that finely ground or powdered paratfin wax and zinc oxide with about 8.0% being zinc oxide will produce satisfactory results, but

Patented-May 14, 1957 the ratio of wax and zinc oxide may be varied to some extent. Likewise, the-hydrogen peroxide may be varied to some extent in concentration. Such variations in materials that produce satisfactory results are considered within the scope of this invention.

In arriving at this invention, a number of different compositions of materials were tried out in the process before a workabl composition of materials was discovered. Of all the compositions tried, the paraflm and zinc oxide composition was the only one that produced satisfactory results. As hydrogen peroxide was used in all cases, it is evident that the invention consists in the method involving both the particular composition and peroxide.

It will be evident that the method set forth is simple and can be carried out in any cleaning establishment or in the home and that it requires only about an hour in time.

It will be understood that this method may be slightly modified or changed without departing from the principles of this invention so I do not propose limiting the patent granted otherwise than necessitated by the appended claims.

Iclaim:

l. The method of removing scorched elfects from a piece of cloth without damage to the cloth and without removing the color of the cloth which method comprises placing the scorched cloth to be treated upon a support to expose the scorched area for treatment, then covering the the entire scorched area with a powdered composition containing a mixture of approximately 92% parafiin wax and approximately 8% zinc oxide; said powdered composition having previously been compounded by melting a quantity of parafiin wax, then adding to the melted wax a quantity of powdered zinc oxide in the approximate proportion of 8% powdered zinc oxide to 92% paraffin wax, then allowing the said mixture of wax and zinc oxide to solidify, then powdering the said solidified mixture; then after the application of said powdered composition sprinkling a solution containing approximately 3% hydrogen peroxide and approximately 97% water over the said applied powdered composition, then rolling the cloth into a roll to substantially enclose therein the treated area, and finally allowing the rolled area to stand for about one hour.

2. The method of removing scorched efiects from cloth without damage to the material and without removing the color of the cloth, which comprises placing the scorched cloth to be treated upon a support with the scorched area exposed, applying approximately one tablespoonful of a powdered composition consisting of approximately 92% parafiin wax in which, in the molten state, has been incorporated approximately 8% of zinc oxide subsequently allowed to solidify and then powdered and spread over the entire scorched area, then sprinkling about two tablespoonfuls of a solution containing approximately 3% hydrogen peroxide and approximately 97% water over the powdered composition on the area to be treated, then rolling the treated area of the cloth into a roll to encompass the materials applied to the treated area and then allowing the rolled portion to stand for about an hour.

3. The method of removing scorched effects from cloth without damage to the material and without removing the color of the cloth, which comprises placing the scorched cloth to be treated upon a support with scorched area exposed, applying approximately one part by volume of a powdered composition consisting of approximately 92% paraflin wax in which in the molten state has been incorporated approximately 8% of zinc oxide subsequently allowed to solidify and then powdered and spread over the entire scorched area, then sprinkling about two parts by volume of a solution containing approximately 3% hydrogen peroxide and approximately References Cited in the file of this patent 97% water over the powdered composition on the area to be treated, then rolling the treated area of the cloth Farmers Bulletin, 1474: P f Agrlculture, into a roll to encompass the materials applied to the September 1942, Stain Removal from Fabflcs,page treated area and then allowing the rolled portion to stand 5 Pharmaceutlcal Formulas, 1944, 1, P

for about an hour. 

1. THE METHOD OF REMOVING SCORCHED EFFECTS FROM A PIECE OF CLOTH WITHOUT DAMAGE TO THE CLOTH AND WITHOUT REMOVING THE COLOR OF THE CLOTH WHICH METHOD COMPRISES PLACING THE SCORCHED CLOTH TO BE TREATED UPON A SUPPORT TO EXPOSE THE SCORCHED AREA FOR TREATMENT, THEN COVERING THE ENTIRE SCORCHED AREA WITH A POWDERED COMPOSITION CONTAINING A MIXTURE OF APPROXIMATELY 92% PARAFFIN WAX AND APPROXIMATELY 8% ZINC OXIDE; SAID POWDERED COMPOSITION HAVING PREVIOUSLY BEEN COMPOUNDED BY MELTING A QUANTITY OF PARAFFIN WAX, THEN ADDING TO THE MELTED WAX A QUANTITY OF POWDERED ZINC OXIDE IN THE APPROXIMATE PROPORTION OF 8% POWDERED ZINC OXIDE TO 92% PARAFFIN WAX, THEN ALLOWING THE SAID MIXTURE OF WAX AND ZINC OXIDE TO SOLIDIFY, THEN POWDERING THE SAID SOLIDIFIED MIXTURE; THEN AFTER THE APPLICATION OF SAID POWDERED COMPOSITION SPRINKLING A SOLUTION CONTAINING APPROXIMATELY 3% HYDROGEN PEROXIDE AND APPROXIMATELY 97% WATER OVER THE SAID APPLIED POWDERED COMPOSITION, THEN ROLLING THE CLOTH INTO A ROLL TO SUBSTANTIALLY ENCLOSE THEREIN THE TREATED AREA, AND FINALLY ALLOWING THE ROLLED AREA TO STAND FOR ABOUT ONE HOUR.
